E-TA2012 T 4DB N4 RF Attenuator Equivalent & Substitute Parts

Part Overview

The E-TA2012 T 4DB N4 is a 4dB RF attenuator manufactured by Nidec Components Corporation, designed for applications requiring signal attenuation across the 0 Hz to 3 GHz frequency range. This component operates at 50 ohms impedance with a power rating of 63mW in a compact 0805 (2012 metric) surface-mount package. The part is currently classified as obsolete, making identification of active equivalent alternatives essential for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution for the E-TA2012 T 4DB N4 is determined by strict equivalence across the following critical parameters:

• Attenuation Value: 4dB (exact match required)
• Frequency Range: 0 Hz ~ 3 GHz (exact match required)
• Impedance: 50 Ohms (exact match required)
• Power Rating: 63mW (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• RoHS Compliance: ROHS3 Compliant (maintained)
• Moisture Sensitivity Level: 1 (Unlimited) (maintained)

All three substitute parts from Susumu (PXV1220S-4DBN1-T02, PXV1220S-4DBN2-T02, PXV1220S-4DBN3-T02) meet these criteria and are classified as active products, providing viable alternatives to the obsolete Nidec component.

Parameter Comparison

Engineering Selection Recommendations

The three Susumu PxV series RF attenuators (PXV1220S-4DBN1-T02, PXV1220S-4DBN2-T02, PXV1220S-4DBN3-T02) are direct parametric equivalents to the obsolete E-TA2012 T 4DB N4. All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with current environmental standards. The active product status of all three Susumu alternatives guarantees long-term availability and supply chain continuity compared to the discontinued Nidec component. Selection among the three Susumu variants may be determined by inventory availability and procurement lead times, as all three are electrically and mechanically identical.

Frequently Asked Questions (FAQ)

Q: Can the Susumu PXV1220S series parts be used as direct replacements for the E-TA2012 T 4DB N4?

A: Yes. All three Susumu variants (PXV1220S-4DBN1-T02, PXV1220S-4DBN2-T02, PXV1220S-4DBN3-T02) are parametric equivalents with identical attenuation, frequency range, impedance, power rating, and package specifications.

Q: What is the difference between the three Susumu substitute parts?

A: The three PXV1220S variants are electrically and mechanically identical. Differences exist only in inventory levels and internal manufacturing designations (N1, N2, N3 suffixes).

Q: Are the substitute parts available in the same packaging format as the original?

A: The Susumu substitutes are supplied in Tape & Reel (TR) format, which is standard for high-volume production. The original E-TA2012 was available in standard packaging. Both formats are compatible with automated assembly equipment.

Q: Do the substitute parts meet the same compliance requirements?

A: Yes. All Susumu PXV1220S variants are ROHS3 compliant and REACH unaffected, matching the compliance profile of the original E-TA2012 T 4DB N4.

Q: Why is the original E-TA2012 T 4DB N4 classified as obsolete?

A: Nidec Components Corporation has discontinued this product line. Active alternatives from Susumu provide equivalent performance and are recommended for new designs and ongoing production requirements.
